The existence of a light dark force mediator has been tested with the KLOE detector at DAPHNE. This particle, called U, is searched for using decay chain phi-->etaU, eta-->pi+pi-pi0, U-->e+e-. No evidence found in 1.5 fb-1 data. resulting exclusion plot covers mass range 5
We report the first observation of rare eta->e+e-e+e- decay based on 1.7 fb^{-1} collected by KLOE experiment at DAFNE phi-factory. The selection e+e-e+e- final state is fully inclusive radiation. have identified 362 +- 29 events resulting in a branching ratio (2.4 0.2_stat+bckg 0.1_syst) x 10^{-5}.
Minority group experiences in urban settings are always subjected to the problem of top-down or external categorisations which related interpersonal and material interactions within city. To catch those interdependencies our research is concerned with whether people externally categorized by us as ‘Muslims’ city Krakow determine motivate their actions relationships mainly on basis religion they engage constant, regular others ‘Muslims’. The aim article twofold. First it highlights need for...
We report the measurement of ratio $\Gamma(\eta \to \pi^+\pi^-\gamma)/\Gamma(\eta \pi^+\pi^-\pi^0)$ analyzing a large sample $\phi \eta \gamma$ decays recorded with KLOE experiment at DA$\Phi$NE $e^+ e^-$ collider, corresponding to an integrated luminosity 558 pb$^{-1}$. The $\eta \pi^+\pi^-\gamma$ process is supposed proceed both via resonant contribution, mediated by $\rho$ meson, and non direct term, connected box anomaly. presence term affects partial width value. Our result...
The processes $e^+e^-\to e^+e^-X$, with $X$ being either the $\eta$ meson or $\pi^0\pi^0$, are studied at DA$\Phi$NE, $e^+e^-$ beams colliding $\sqrt{s}\simeq1$ GeV, below $\phi$ resonance peak. data sample is from an integrated luminosity of 240 pb$^{-1}$, collected by KLOE experiment without tagging outgoing $e^+e^-$. Preliminary results presented on observation $\gamma\gamma\to\eta$ process, both $\eta\to\pi^+\pi^-\pi^0$ and $\eta\to\pi^0\pi^0\pi^0$ channels, evidence for...
Neutral kaons produced in correlated pairs at a phi-factory offer unique possibilities to perform fundamental tests of CPT invariance, as well the basic principles quantum mechanics. The analysis data collected by KLOE experiment DAFNE is still ongoing with aim improving previous results and limits on several parameters describing violation decoherence. Ancillary measurements like regeneration cross section beam pipe materials are also progress will be very useful reduce systematic...
